Hold meeting with geologist, core hand and TP to confirm procedures
Before dropping the ball insure that there is no restriction in the string. (mud check valve etc)

Core Recovery / Handling Procedures for recovering and transporting unconsolidated core
Refer to Wellsite Coring Guideline document

Ensure rig crew are aware of method to trip core from hole e.g. min rotation, jarring etc
Prior to laying out of the core, hold informal meeting with key personnel and rig crews to discuss safe, effective handling procedures
Ensure geologist has all necessary equipment and a suitable area to process the core
Have crane driver ready to assist laydown and make sure he understands his task
